"Could not load file or assembly 'file:///C:\OutSystems\Sandboxes\KD69V5013\Platform Server\running\IDCard\bin2\PublicDataParser.DLL' or one of its dependencies. An attempt was made to load a program with an incorrect format."

I have included PublicDataParser.DLL via Integration Studio to my application.

1) You used the x86 version of the dll's instead of the x64 versions.
PublicDataParser.dll (x64) - Throws error while importing actions from .Net Assembly Wizard.
"'<path>\PublicDataParser.dll' is not a valid .Net Assembly"
Whereas, x86 version dll extracts the Parser class from the dll.2) You did not include some dependency dll in you extension. You can use a tool like Dependency Walker to check what are it's dependencies.
No dependencies for the dll.3) The dll requires other components installed in the machine (a native driver for example). This one will be hard to solve in a Personal Cloud environment, since it involves installing solftware there
Tried to copy the same dll to the path where it failed to load the dll. But still, i get the same error message"Could not load file or assembly 'file:///C:\Program Files\Outsystems\Platform Server\running\EID\bin2\PublicDataParser.DLL' or one of its dependencies. An attempt was made to load a program with an incorrect format."
